Cage of Self

A creature of your choice that you can see within range must succeed on an Wisdom saving throw to avoid being affected by this spell.

While under the effect of this spell, the creature gets disavantage on attack rolls and Strength and Dexterity saving throws. In addition, all the creature's movement speeds are reduced to half and is not able to cast spells that require somatic components, since the shake won't allow the gestures to be performed correctly.

At the end of each of its turns, and each time it takes damage, the target can make another Wisdom saving throw. The target has advantage on the saving throw if it’s triggered by damage. On a success, the spell ends.

This spell does not affect creatures with disform bodies like Ozzes nor creatures currently poisoned.
